Only four copepod species associated with sea stars have beenknown from the north Pacific . The examination of Korean sea stars for copepod associates revealed two species ; Scottomyzson gibberum and a new species belonging to the genus Synstellicola. Both species are (re) described. S. gibberum , A sole member of the genus hitherto known only from the northeastern Atlantic , is recorded in this report to be associated with various sea stars and distributed widely in Korean seas.

We performed conservation treatment for the sarira reliquary from the pagoda of Hwangnyongsa temple site. The sarira reliquary is in the shape of gilt-bronze octagonal miniature pagoda. Through radiography, it was newly proved that a radial design exists on the roof part. The gilded layer was plated with amalgam. Each part was plated first before being put together. We restored the lost parts and made supports, and then assembled it in the following order: base, upper part of the base, shaft and roof part.

This study is aimed at classifying the syntaxa of Ceratopteris thalictroides dominant community on the Nakdong River, and to collect basic data for research of habitat. The communities were carried out by using the Z.-M. School's method and numerical classification technique. The result of syntaxa was classified three communities such as Persicaria japonica-Ceratopteris thalictroides community, Lindernia procumbens-Ceratropteris thalictroides community, and Limnophila indica-Ceratopteris thalictroides community. The ordination analysis displayed the vegetation types with respect to complex environmental gradients. After ordination and clustering analysis, the effective humidity, soil stability, trampling effects, anthropogenic effects and flooding frequency were identified as the important factors deciding the vegetation pattern. It was pointed out to establish a long-term ecological site for protecting such vulnerable vegetation against overexploitation and global climate change.

국내 주요하천은 지속적인 산업화와 난개발로 인해 생태계파괴 및 수변생물의 서식처 환경 악화로 하천 생태계에 많은 악영향을 받고 있다. 그러나 1990년대 이후 국내에서는 하천의 기능과 생물의 다양성, 하천환경 및 생태학적인 가치와 중요성에 대한 인식이 매우 커짐에 따라 하천의 생태적 기능을 매우 중요시 하고 있으며, 하천의 난개발로 인한 피해를 복원하기 위해 활발한 연구가 진행되고 있다. 대표적인 연구로 생태계 건전화 개념을 도입하여 담수성 어류 서식처 제공 및 이동에 필요한 유량을 산정한 한국 수자원공사(1995)의 연구가 있으며, 김규호 등(1996a, 1996b)은 물고기 서식처 환경 중 특히 수심과 유속 등 수리조건을 유지하기 위한 최소유량 산정 방법을 제시하였다. 또한 노경범(2011)은 섬진강의 하천환경 회복을 위한 연구대상 구간에서의 대표어종을 선정하여 서식처 특성 파악을 위해 하천 특성을 연구하였다. 이와 같이 현재 국내에서도 하천의 기능과 생태학적 기능을 위한 노력과 연구가 진행되고 있다. 그러나 생태학적 서식처 연구에서는 아직까진 미진한 부분이 많이 있다. 그 예로 보호종이나 멸종위기어종과 같은 생물의 서식처 확보를 위한 연구가 아직까지는 많은 노력과 연구가 필요한 상태이다. 본 연구에서는 환경부에서 지정한 멸종위기 1급 어종인 퉁사리를 대상으로 서식환경 특성 연구를 진행하였으며, 퉁사리의 생태학적 서식특성과 현재 지석천 상류 유역에서 관찰되고 있는 서식구간을 중심으로 MD-SWMS (Multi-Dimensional, Surface Water Modeling System) 모형을 이용하여 수리특성 분석을 수행하였다. 이를 위해 하상재료 입도분석을 실시하였으며, 그 결과 입도가 큰 굵은모래 및 잔자갈, 굵은자갈로 구성되어 있음을 알 수 있었다. 또한, 수리학적 특성분석결과 서식구간 내에서는 비교적 빠른 유속이 나타났다. 이러한 퉁사리의 서식환경의 특성 분석으로 서식구간 내 입도가 큰 하상재료로 구성되어 있으며, 퇴적구간이 생성되지 않을 정도의 유사이송량과 유속이 필요할 것으로 분석되었다. 향후 퉁사리의 장기적인 서식환경 조성과 보존을 위해 대상구간의 유사이송의 연구와 실측 및 수변환경 모니터링을 통한 다양한 연구가 진행되어야 할 것으로 판단된다.

The current study was conducted to confirm the anti-cancer effect of Sarijang, which is a mixture of extracts from purple bamboo salt, Rhynchosia nulubilis, garlic, and Ulmi cortex. Nude mice were injected with a human-derived colorectal cancer cell (HCT116 cell line) and subsequently administered Sarijang for 4 weeks, following which the body weight, organ weight, and tumor size were measured. To evaluate the anti-cancer mechanism of Sarijang, the levels of p16 and extracellular signal-regulated kinase (ERK), cell cycle regulators in colorectal cancer, were measured. To evaluate the toxicity of Sarijang on liver and kidney, aspartate transaminase, alanine transaminase, blood urea nitrogen, and creatinine were analyzed. Sarijang not only reduced the tumor size by enhancing p16 and suppressing ERK, but also showed no side-effect in the liver and kidneys. Taken together, Sarijang has the potential to inhibit tumor growth without side effects, and may be used as a useful functional food.

Three species of Rhodophyceae namely Chondrus ocellatus, Grateloupia filicina and Gigartina tenella were collected from the coast of Haeundae, Busan, on June 33, 1975. And analysed with respect to the content of carrageenan and such chemical characteristics as the content of sulphate and 3, 6-anhydrogalactose, the solubility in potassium chloride solution. In addition, the same chemical properties were tested on the fractions separated by the different concentration of potassium chloride. Carrageenan content in Chondrus ocellatus was relatively higher than two other samples. All the samples showed more than thirty five percent. The Gigartina-carrageenan showed the highest 3,6-anhydrogalactose content among three samples of carrageenan obtained from different species, and the lowest marked from the Grateloupia-carrageenan. In comparison of the solubility of carrageenan in potassium chloride solution, the precipitation yields at 0.125M potassium chloride were marked in order of Chondrus-carrageenan, Grateloupia-carrageenan, and Gigartina-carrageenan, and the yields at 0.125 M to 2.0 M potassium chloride were in Gigartina-carrageenan, Grateloupia-carrageenan, and Chondrus-carrageenan, and the yields from the soluble fraction at 2.0 M potassium chloride were in order of Grateloupia-carrageenan, Gigartina-carrageenan, and Chondrus-carrageenan. It is noteworthy from the result of characteristics of carrageenans that, 3,6-andydrogalactose content was closely related to the solubility of carrageenans in potassium chloride solution and to the sulphate content which might affect reversibly.

The sarira reliquary excavated as a lot of fragments were restored by conservation treatment by us. The sarira reliquary was made using fine techniques such as chasing work and engraving work, etc. The analysis of base metals showed that different materials had been used on decorative parts in consideration of the casting and forging technique. Gold granules $(97wt\%\;Au)$ of the small bell were adhered by using a soldering material $(85wt\%\;Au,\;10wt\%\;Ag)$. The lead isotope analysis of lead glass $(74wt\%\;PbO)$ revealed that it agreed with the lead mine in the middle of south area in Korea.

The chromosome numbers of five species in two families of Korea are investigated: Odontobutis platycephala, O. interrupta, and O. obscura in Odontobutidae, and Cottus koreanus and C. hangiongensis in Cottidae. In Odontobutis species, the three species showed the diploid chromosome number, 2n=44 (NF=44) telocentric chromosomes. In Cottus species, the mitotic chromosomes from 24 groups with two chromosomes each indicated that it is a diploid. The karyotype of C. koreanus and C. hangiongensis is 2n=48 and NF=52. These species is the first report on the chromosomes and the karyotype analysis except O. platycephala. Our findings provide cytotaxonomic evidence for the species distinctness of these five species whose descriptions were based primarily on external morphology.

The purpose of this study is to verify relationships among attributes of ramen package design, ramen image, and chinese customer's choice of ramen. We chose, as a sample, ramen 'sour ramen', 'squid jjambbong', 'tasty ramen', 'noodle beef soup', and 'seasame ramen'. The findings and implications can be summarized as follows. first, while chinese customers chose 'sour ramen' as the most favorable ramen, followed by 'tasty ramen', 'squid jjangbbong', 'noodle beef soup', and 'seasame ramen', for ramen image they most highly evaluated 'sour ramen' followed by 'squid jjangbbong', 'tasty ramen', 'seasame ramen', and 'noodle beef soup'. Second, there is a significant difference in popularity and reliability of quality, but no significant difference in attractiveness and healthiness among most attributes of ramen package design. Third, compared to 'seasame ramen', the popularity and reliability of quality for 'sour ramen', reliability of quality for 'squid jjangbbong', reliabilty of quality, and healthiness for 'tasty ramen' had positive effect on choice, while attractiveness for 'noodle beef soup' had a negative effect on their choice.
